06 Rear Hatch/Window going down on its own

[mpho]

Hello. I have an 06 4 runner and the rear window started to go down on its own. I will shut off the car and 2-3 minutes later, the rear window goes down. Doesn't happen all the time. There is a beep usually before it descends.

Thoughts? Ideas? Thanks in advance.

Stuck button in key fob maybe? Try another one or take out the battery for a bit and see if it goes away... Maybe your SO is hitting the button with the other key fob just to drive you nuts?
